Alexandru Croitor 37b132cd4e CMake: Fix standalone tests to work properly on reconfiguration
And also fix qt-cmake-standalone-test to work for prefix builds.

The gist of it is that we have to protect tests not to be installed
into the Qt install prefix, but we also have to make sure that the
CMAKE_INSTALL_PREFIX is not changed globally (via cache value),
so that reconfiguration still works.

This took way too long to figure out.
